Performance of Suspended Nonstructural Components and Their Anchorage during Shake Table Tests

Nonstructural components and systems are typically connected to concrete structures by means of post-installed anchors. Despite their widespread use, very little is known about the behavior of post-installed anchors when used in a system and loaded during an earthquake. The study presented in this paper was conducted to investigate the seismic performance of suspended model non-structural components connected by post-installed anchors to a concrete slab. The concrete slab was mounted in a special loading rig on a shake table and subjected to a series of floor motions simulating the acceleration histories at specific floor levels of typical reinforced concrete buildings of variable heights. Simultaneously, the anchors supporting the component were set in predefined cracks, which opened and closed according to pre-calculated crack histories. This unique test setup allowed evaluation of the performance of anchors and attached components under realistic boundary and loading conditions.
